 CDAP
 ======================
 
-Overview of my blueprint and the part it plays in DCAE.
+Note: This blueprint is intended to be deployed, automatically, as part of the
+DCAE bootstrap process, and is not normally invoked manually.
 
-Blueprint files
-----------------------
+The ONAP DCAEGEN2 CDAP blueprint deploys a 7 node Cask Data Application
+Platform (CDAP) cluster (version 4.1.x), for running data analysis
+applications.  The template for the blueprint is at
+``blueprints/cdapbp7.yaml-template`` in the ONAP
+``dcaegen2.platform.blueprints`` project.  The ``02`` VM in the cluster
+will be the CDAP master.

-Parameters
+Blueprint Input Parameters
 ---------------------
 
-The input parameters needed for running the blueprint
+This blueprint has the following required input parameters:
 
-How To Run
----------------------
+* ``ubuntu1604image_id``
 
-Cfy command for running the blueprint
+  This is the OpenStack image ID of the Ubuntu 16.04 VM image that will be
+  used to launch the 7 VMs making up the cluster.
 
-Additional Information
----------------------
-Any additional information that help other people understanding and using yor blueprint
+* ``flavor_id``
+
+  This is the OpenStack flavor ID specifying the amount of memory, disk, and
+  CPU available to each VM in the cluster.  While the required values will be
+  largely application dependent, a minimum of 32 Gigabytes of memory is
+  strongly recommended.
+
+* ``security_group``
+
+  This is the OpenStack security group specifying permitted inbound and
+  outbound IP connectivity to the VMs in the cluster.
+
+* ``public_net``
+
+  This is the name of the OpenStack network from which floating IP addresses
+  for the VMs in the cluster will be allocated.
+
+* ``private_net``
+
+  This is the name of the OpenStack network from which fixed IP addresses for
+  the VMs in the cluster will be allocated.
+
+* ``openstack``
+
+  This is the JSON object / YAML associative array providing values necessary
+  for accessing OpenStack.  The keys are:
+
+  * ``auth_url``
+
+    The URL for accessing the OpenStack Identity V2 API.  (The version of
+    Cloudify currently being used, and the associated OpenStack plugin do
+    not currently support Identity V3).
+
+  * ``tenant_name``
+
+    The name of the OpenStack tenant/project where the VMs will be launched.
+
+  * ``region``
+
+    The name of the OpenStack region within the deployment.  In smaller
+    OpenStack deployments, where there is only one region, the region is
+    often named ``RegionOne``.
+
+  * ``username``
+
+    The name of the OpenStack user used as a credential for accessing
+    OpenStack.
+
+  * ``password``
+
+    The password of the OpenStack user.  (The version of Cloudify currently
+    being used does not provide a mechanism for encrypting this value).
+
+* ``keypair``
+
+  The name of the ssh "key pair", within OpenStack, that will be given access,
+  via the ubuntu login, to the VMs.  Note: OpenStack actually stores only the
+  public key.
+
+* ``key_filename``
+
+  The full file path, on the Cloudify Manager VM used to deploy this blueprint,
+  of the ssh private key file corresponding to the ``keypair`` input parameter.
+
+* ``location_domain``
+
+  The DNS domain/zone for DNS entries associated with the VMs in the cluster.
+  If, for example, location_domain is ``dcae.example.com`` then the FQDN for
+  a VM with hostname ``abcd`` would be ``abcd.dcae.example.com`` and a DNS
+  lookup of that FQDN would lead an A (or AAAA) record giving the floating
+  IP address assigned to that VM.
+
+* ``location_prefix``
+
+  The hostname prefix for hostnames of VMs in the cluster.  The hostnames
+  assigned to the VMs are created by concatenating this prefix with a suffix
+  identifying the individual VMs in the cluster (``cdap00``, ``cdap01``, ...,
+  ``cdap06``).  If the location prefix is ``jupiter`` then the hostname of
+  the CDAP master in the cluster would be ``jupitercdap02``.
+
+* ``codesource_url`` and ``codesource_version``
+
+  ``codesource_url`` is the base URL for downloading DCAE specific project
+  installation scripts.  The intent is that this URL may be environment
+  dependent, (for example it may, for security reasons, point to an internal
+  mirror).  This is used in combination with the ``codesource_version`` input
+  parameter to determine the URL for downloading the scripts.  There are 2
+  scripts used by this blueprint - ``cdap-init.sh`` and
+  ``instconsulagentub16.sh`` These scripts are part of the
+  dcaegen2.deployments ONAP project.  This blueprint assumes that curl/wget
+  can find these scripts at
+  *codesource_url/codesource_version*\ ``/raw/cloud_init/cdap-init.sh`` and
+  *codesource_url/codesource_version*\ ``/raw/cloud_init/instconsulagentub16.sh``
+  respectively.  For example, if codesource_url is
+  ``https://mymirror.example.com`` and codesource_version is ``rel1.0``,
+  then the installation scripts would be expected to be stored under
+  ``https://mymirror.example.com/rel1.0/raw/cloud_init/``
+
+This blueprint has the following optional inputs:
+
+* ``location_id`` (default ``solutioning-central``)
+
+  The name of the Consul cluster to register this CDAP cluster with.
+
+* ``cdap_cluster_name`` (default ``cdap``)
+
+  The name of the service to register this cluster as, in Consul.
